Notices:

Periodic Upkeep: Highland Heavy Duty Hydraulic Motors are built for strenuous scenarios, but that doesn't negate the need for regular upkeep to ensure their longevity and optimal performance. Key maintenance tasks include checking and topping up hydraulic fluid as required, periodically inspecting the motor for any signs of wear or potential damage, and addressing any emerging issues without delay. Failure to adhere to a regular upkeep schedule can result in dwindling efficiency, increased wear and tear, and potential risk of motor malfunction.

Application:

Mixer truck: concrete mixer truck, cement mixer truck;

Coal mining machinery: scraper;

Industry: pharmaceutical machinery;

Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers

HMF70 Engineering Drawing

The HMF70-21 uses the HMF70/90 series motor drawing. Its output shaft is an involute spline with 21 teeth at 16/32 radial pitch and a 30° pressure angle (dividing circle diameter 33.34 mm). The SAE flange is held by four M12 bolts, 25 mm deep. L1 and L2 are the leakage ports; the speed-sensor port takes 7/8-14 UNF-2B; and the flushing pressure measuring port and relief-valve pressure taps are 9/16-18, 15 mm deep. CW and CCW rotation are both offered.

HMF70 Factory Production & Inspection Evidence

The factory documents the production and inspection of every HMF70-21 motor and photographs the unit on the shop floor before it ships; the evidence is listed below.

Factory Evidence

• Hydraulic motor photographed on the factory floor before dispatch
• Housing and drive shaft given a visual check ahead of shipment
• Port and mounting layout verified against the HMF70 specification
• Final inspection completed to the product's technical requirements

Evidence Type: Factory Production / Visual Inspection

Application: Mobile crusher hydraulic drive

Product Status: Production / Pre-shipment Inspection

HMF70 Factory Performance Testing

Every HMF70-21 is run on the closed-loop bench before shipment. Component No. 02604110203003 was tested on 2026/4/11 10:23 at 36.2 ℃ at the 70 mL/rev rated displacement, 3200 r/min maximum speed and 38 MPa maximum pressure (rated 35 MPa); the power-recovery ratio recorded is 40 %.

HMF70 Recorded Test Data

Bench readings for the HMF70-21 motor, exactly as recorded (component No. 02604110203003; 2026/4/11 10:23; 36.2 ℃; charge pressure 1.1 MPa):

The figures above are taken unaltered from the factory test report, with charge pressure held at 1.1 MPa.

HMF70 Quality Control & Inspection

Every HMF70-21 follows the same inspection sequence. After assembly it is bench-run on the closed-loop motor stand, where displacement, working pressure, speed, flow and torque are logged, overall and volumetric efficiency are confirmed, and leakage is checked; the unit is approved only when all readings are within specification.

HMF70 Application / Project Evidence

The HMF70-21 closed axial piston motor was manufactured for a cotton harvester programme in Kyrgyzstan. The order — logged internally as “Variable Piston Pump for Kyrgyzstan” — came to 60 units, delivered to a Kyrgyzstan-based customer and made by Shandong Highland Hydraulic Seiko Co., Ltd. On this product the motor drives the mobile crusher hydraulic drive within the closed-circuit hydrostatic transmission. The details below are taken from that delivery's project records.

HMF70 Technical Documents

A set of technical documents backs the HMF70 motor, recording its performance ratings, test evidence and installation dimensions. The documents held for this product are listed below and can be supplied to qualified buyers on request.

• HMF70 motor technical parameter sheet
• Closed-loop hydraulic motor test report (component No. 02604110203003)
